> Vast majority of the CS grads won't even need to use most of what theyre taught, when they finally land a job.
Should they? A material science graduate isn't expected to use much of what they learned when they get a job as welder either. CS is for those interested in the academic pursuit of the sciences. It is not for vocational training.
You still need some way to keep out the poor and underprivileged who are not good for business. Overtly stating they are not welcome doesn't fly anymore, but rejecting anyone who isn't in a position to be able to casually engross themselves in the sciences for several years for no reason other than personal enjoyment is a decent proxy.
